How do you determine your fitting size?

You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).

How are inner threads measured?

To identify an inside thread (such as a filter ring on a lens), first take your best guess from age and origin to determine if its a metric thread then measure the diameter of the female (inside) thread. Take (The “Minor Diameter”) then add the pitch number to the measurement.

What are the types of fittings?

What is Dash thread size?

Simply put, a dash size refers to an I.D. of a hydraulic hose or fitting in 1/16″ increments. For example, -6 hose would indicate a hose with I.D. of 6/16″ – or 3/8″. Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter.

What does an stand for in fittings?

AN stands for Air Force – Navy Aeronautical Design Standards (also known as “Army Navy”) that are used in U.S. Military aviation applications. These fittings are made to meet strict performance standards related to the aeronautical industry.

What is the smallest NPT size?

Sizes smaller than 1⁄8 inch are occasionally used for compressed air, while sizes larger than 6 inches are often joined by other methods.

Is JIC and an the same?

JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.

Do JIC fittings need Teflon tape?

Registered User. You don’t need or should use any teflon tape or pipe dope on hydraulic fittings. Neither are designed for those kinds of pressures and using them could create a less then perfect mating between connection surfaces causing more harm than good.

ARE AN fittings 37 degree?

AN fittings are manufactured to meet above standards. These fittings include the 37° flare, flareless, hose connections, “banjo” type fittings, specialized flange fittings, pipe fittings and other types of connections.

How are threads measured?

StepsMeasure an inch-long portion of the threaded area. Grab a ruler and lay it along the bolt or screw. … Count the number of threads in 1 inch. … Measure the diameter and the length of the threaded area. … Plug the information into a standard measurement.

Is flare the same as NPT?

Aside from thread sizes, the most important difference between AN and NPT threaded fasteners is that NPT uses a tapered thread. … On the other hand, AN fittings are flare-type compression fittings and, as such, don’t require any form of thread sealant.

How do you calculate threads per inch?

Measuring Imperial Thread Pitch As the name suggests, TPI is measured by counting the number of thread peaks along a 1 inch length. The TPI measurement is then often affixed to the diameter of the thread to form a common imperial thread size, e.g. ‘1/4-20’, which would denote a ¼ inch diameter, and 20 threads per inch.

Are brake lines NPT?

National Pipe Thread is a tapered machine thread for threaded pipes and fittings . NPT threads can be referred to as “Male pipe thread” or “Female pipe thread”. … We use these in the Street Rod and Racing industries for fluid fittings such as oil lines, brake lines, and coolant lines.

What is 4AN fitting?

-4AN = 4/16″ = 1/4″ ID hose, fittings use 7/16-20 SAE thread. You can measure that with a ruler; 3/8-24 is 3/8″ outer diameter with 24 threads per inch. Save Share. Reply.

What is an NPT fitting?

NPT (or National Pipe Taper) is a U.S. standard for tapered threads widely used on pipes and fittings for over 100 years. NPT connections rely on thread deformation- a metal to metal sealing design where the threads of the connectors themselves form together.
